New Orleans Police have released additional details regarding the death of Muhiydin D'Baha Moye, a Charleston-area Black Lives Matter activist shot and killed Tuesday morning.

A police officer answering a call about gunfire early Tuesday found Moye, 32, on the ground, asking for help near the Treme neighborhood, about eight blocks from the French Quarter, according to a police report.

The report says a blood trail to where Moye collapsed in the street spanned two blocks, and a bloody bicycle lay across the street from where Moye fell. The shooting happened along the 1900 block of Bienville Street, where officers say they found a spent bullet fragment.

The responding officer saw a traffic camera and a car repair business's surveillance camera in the area, according to the police report. Officials did not say if the camera captured images that might help the investigation.

Moye was shot in the thigh. He later died in a local hospital, New Orleans police spokesman Beau Tidwell said Wednesday. It was not immediately clear what led to the shooting.

At the time, demonstrations were going on outside a theater at the College of Charleston for a speech by Bree Newsome, an activist who climbed a flagpole and temporarily removed a Confederate flag from in front of the South Carolina Statehouse in 2015.

DeRay Mckesson, a prominent figure in the Black Lives Matter movement, said Moye was a fearless, kind man whose death is a big loss for Charleston and for BLM.

McKesson said he met Moye in 2015, after the fatal shooting of Walter Scott, an unarmed black man, by white North Charleston police officer Michael Slager.

"He was a strong leader who deeply understood the role of community and the power of helping other people recognize that role," Mckesson said.

Moye was taking a personal trip to New Orleans, Moye's niece Camille Weaver told ABC News 4 Tuesday. She told The Post & Courier Moye was born in Poughkeepsie, New York, and grew up in Hollywood, South Carolina.

"He loved Charleston and loved fighting for what's right," she said. "I've never met anyone more committed and hardworking than him. He was an asset to the Charleston community and will be greatly missed."

An activist at a vigil Tuesday said Moye is irreplaceable.

"The intellectualism, the fire, the desire, the motivation, the way he rallied people in the city was just second to none," Johnathan Thrower said.

A GoFundMe fundraiser site has been established by Moye's family to help with funeral costs and to transport his body back to South Carolina.
